About This Chapter
Earth's Material Resources - Chapter Summary
This chapter will teach students all about Earth's material resources, with lessons on the wilderness, water resources and rocks and soil. The short video lessons typically last between five and ten minutes each, so students can focus on each topic individually before moving on to the next. Lessons can be watched and rewatched until the concept is mastered, and feature an interactive timeline that can be used to quickly jump to specific points.
|What Is Wilderness? - Definition, Problems & Preservation||Look at the problems that face wilderness areas and wilderness conservation.|
|What Are the Properties of Water? - Unique Properties that Support Life on Earth||Explore the properties of water and how it makes life on Earth possible.|
|Water Resource Issues: Activities Affecting the Water Supply||Address threats to the water supply.|
|Properties of Ocean Water||Learn all about ocean water and its unique properties.|
|Groundwater System: Definition & Geological Role||Examine the groundwater system and its role in shaping the surface of the earth.|
|What is Soil? - Definition, Structure & Types||Discuss soil composition and different types of soil.|
|Rocks and Minerals: Definitions and Differences||Learn about the different types of rocks and minerals.|
|Rock Cycle: Igneous, Sedimentary, and Metamorphic rocks||Explore how rocks transition to new forms in the rock cycle.|
|Types of Rocks: The Three Major Rock Groups||Identify the three main rock groups.|
|The Origin of Materials in Common Objects||Discover where materials found in everyday items come from.|
1. What Is Wilderness? - Definition, Problems & Preservation
The wilderness is the last untamed land found on earth. It remains undeveloped by man and serves as a refuge for wildlife. Learn about the wilderness, the law enacted to preserve it and the problems that wilderness areas face.
2. What Are the Properties of Water? - Unique Properties that Support Life on Earth
In this video lesson you will learn about water and its unique properties. You will also develop an understanding of how these properties make life as we know it possible.
3. Water Resource Issues: Activities Affecting the Water Supply
This video lesson describes water resources issues such as aquifer depletion, overdrawing surface waters and salinization of irrigated soil. You will also learn about the impacts of activities affecting water resources.
4. Properties of Ocean Water
Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.
5. Groundwater System: Definition & Geological Role
Surprisingly, most of Earth's liquid freshwater is not where you might think! In this video lesson, you will learn about groundwater, as well as the important roles it plays in sustaining life and shaping Earth.
6. What is Soil? - Definition, Structure & Types
Soil is the material found on the surface of the earth that is composed of organic and inorganic material. Soil varies due to its structure and composition. Learn about the different types of soil and soil structures in this video lesson.
7. Rocks and Minerals: Definitions and Differences
Can you tell the difference between a rock and a mineral? What makes a mineral so much different from a rock? Explore these questions in depth, and learn how we classify rocks and minerals.
8. Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks
In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked in rocks can be cycled through the earth.
9. Types of Rocks: The Three Major Rock Groups
Did you know that lava is molten rock that reaches the earth's surface? Furthermore, did you know that rocks exist in three general forms: igneous, sedimentary and metamorphic? This lesson describes these rock types and examples of each.
10. The Origin of Materials in Common Objects
Learn about the material resources used in everyday objects, and from where those materials were originally collected. Then see how much knowledge you've collected by taking a quiz.
